-description: |
-  Self-check a snapshot-based task for whether the snapshot session leaks the
-  rubric's intended answer to the test agent. `/create-snapshot` is meant to
-  capture a failure mode the task tests recovery from — not extra context
-  that hands the test agent a roadmap to the answer the rubric scores. Run
-  this skill on your task before submission to catch leaks while you can
-  still fix them.

-# Snapshot-leakage detector
-
-This skill checks one of your tasks for snapshot leakage — the most common
-failure mode for snapshot-based tasks, where the prior conversation in
-`session.jsonl` already contains the answer the rubric is testing for, so the
-test agent gets full credit by repeating something the snapshot handed them.
-
-Read these before deciding:
-
-1. `.claude/skills/_detector-worker-shell.md` — where to write the report and how to handle re-runs.
-2. `.claude/skills/detector-snapshot-leakage/core.md` — what this detector looks for, the three shapes a leak can take, verdict enums, frontmatter/body schema.
-
-Compose the report per the schema in `core.md` and write it per `_detector-worker-shell.md`.
-
-## Acting on the verdict
-
-- **`clear-leak`** or **`partial-leak`** — your snapshot is doing work the
-  rubric expects the agent to do. The fix is usually to trim the snapshot
-  (cut the assistant turns that articulate the answer) and replace them with
-  prior conversation that sets up the *failure mode* without resolving it. Re-run
-  this skill after editing to confirm the verdict moved to `clean`.
-- **`clean`** — the snapshot stops short of giving the answer. Good.
-- **`not-applicable`** — the snapshot or rubric is missing/empty. Either
-  this isn't a snapshot task, or the rubric isn't drafted yet. Come back to
-  this skill once both artifacts exist.
